This function, together with ibec_not, ibec_and and ibec_xor, performs bitwise manipulation on integer operands.
function ibec_or(Operand1, Operand2 : integer) : integer;
If the value stored in X (in binary) is 001101 and the value stored in Y is 100001, the statement
Z = ibec_or(X, Y);
assigns the value 101101 to Z.
